Chemical nomenclature is perceived to be a closed topic. However, this work shows that the identification of polyanionic groups is still ambiguous and so is the nomenclature for some ternary compounds. Two examples, boron phosphate (BPO4) and boron arsenate (BAsO4), which were assigned to the large phosphate and arsenate families, respectively, nearly a century ago, are explored. The analyses show that these two compounds should be renamed phosphorus borate (PBO4) and arsenic borate (AsBO4). Beyond epistemology, this has pleasing consequences at several levels for the predictive character of chemistry. It paves the way for future work on the possible syntheses of SbBO4 and BiBO4, and it also renders previous structure field maps completely predictive, allowing us to foresee the structure and phase transitions of NbBO4 and TaBO4. Overall, this work demonstrates that quantum mechanics calculations can contribute to the improvement of current chemical nomenclature. Such revisitation is necessary to classify compounds and understand their properties, leading to the main final aim of a chemist: predicting new compounds, their structures and their transformations.

This chapter introduces the theme of the book: scientific understanding. Science is arguably the most successful product of the human desire for understanding. Reflection on the nature of scientific understanding is an important and exciting project for philosophers of science, as well as for scientists and interested laypeople. As a first illustration of this, the chapter sketches an episode from the history of science in which discussions about understanding played a crucial role: the genesis of quantum mechanics in the 1920s, and the heated debates about the intelligibility of this theory and the related question of whether it can provide understanding. This case shows that standards of intelligibility of scientists can vary strongly. Furthermore, the chapter outlines and defends the way in which this study approaches its subject, differing essentially from mainstream philosophical discussions of explanatory understanding. It concludes with an overview of the contents of the book.

The existing multisensory literature suggests that the combination of the different human senses in a controlled fashion during food/drink experiences can provide more enjoyment to consumers. The present research reviews recent literature relating multisensory perception with wine experiences, focusing on the interaction of the five basic senses (taste, smell, vision, touch, and sound). This is mostly being assessed from a perceptual and behavioral consumer perspective. Here, the authors report different ways in which such interactions across these senses can affect the way a wine is experienced, prior to, during, and even after tasting. The authors finish this literature review by providing some insights in the context of wine and food pairing, while also generally reflecting on potential future work. These insights may be inspirational for a diverse group of organizations working with wine. Based on such multisensory approaches, it may be possible to bring unforeseen sensations to the different wine experiences, while at the same time stressing particular sensory and/or emotional attributes.

NMR- and MS-guided metabolomic mining for new phytoconstituents from a widely used dietary supplement, <i>Rhodiola rosea</i>, yielded two new (+)-myrtenol glycosides, <b>1</b> and <b>2</b>, and two new cuminol glycosides (<b>3</b> and <b>4</b>), along with three known analogues (<b>5</b>–<b>7</b>). The structures of the new compounds were determined by extensive spectroscopic analysis. Quantum Mechanics-driven <sup>1</sup>H iterative Full Spin Analysis (QM-HiFSA) decoded the spatial arrangement of the methyl groups in <b>1</b> and <b>2</b>, as well as other features not recognizable by conventional methods, including higher order spin-coupling effects. The application of QM-HiFSA will provide a definitive reference point for future phytochemical and biological studies of <i>R. rosea</i> as a resilience botanical. Application of a new NMR data analysis software package, CT, for QM-based iteration of NMR spectra is also discussed.

This chapter presents the way to design a learning support system toward acquiring a creative skill on learning. There are two research goals. One is to establish designing the creative learning task. The other is to make clear the human sense of creativity. As the background of this research, the jobs with high creativity or social skills will remain in the future. However, acquiring human's creativity is too difficult for computers. To solve this problem, the authors focus on the way to utilize higher creativity of human than that of computers. The main method is the visualization of learning traces to support awareness for creativity on the learning. The authors conducted the preliminary learning experiment with three human subjects. After that, the questionnaire and the hearing investigation were conducted. As the future work, the authors are planning to conduct an updated version of the experiment.

New computing and networking technologies have not only changed the way traditional crimes are committed but also introduced completely brand new “cyber” crimes. Cyber crime investigation and forensics is relatively a new field that can benefit from methods and tools from its predecessor, the traditional counterpart. This chapter explains the problem of cyber criminal profiling and why it differs from ordinary criminal profiling. It tries to provide an overview of the problem and the current approaches combined with a suggested solution. It also discusses some serious challenges that should be addressed to be able to produce reliable results and it finally presents some ideas for the future work.

Quantum mechanics is a groundbreaking theory: it not only is extraordinarily empirically adequate but also is claimed to having shattered the classical paradigm of understanding the observer-observed distinction as well as the part-whole relation. This, together with other quantum features, has been taken to suggest that quantum theory can help one understand the mind-body relation in a unique way, in particular to solve the hard problem of consciousness along the lines of panpsychism. In this chapter, after having briefly presented panpsychism, Valia Allori discusses the main features of quantum theories and the way in which the main quantum theories of consciousness use them to account for conscious experience.

We introduce a new semirelativistic quantum operator for the length of the worldline a particle traces out as it moves. In this article the operator is constructed in a heuristic way and some of its elementary properties are explored. The operator ends up depending in a very complicated way on the potential of the system it is to act on so as a proof of concept we use it to analyze the expected distance traveled by a free Gaussian wave packet with some initial momentum. It is shown in this case that the distance such a particle travels becomes light-like as its mass vanishes and agrees with the classical result for macroscopic masses. This preliminary result has minor implications for the Weak Equivalence Principle (WEP) in quantum mechanics. In particular it shows that the logical relationship between two formulations of the WEP in classical mechanics extends to quantum mechanics. That our result is qualitatively consistent with the work of others emboldens us to start the task of evaluating the new operator in nonzero potentials. However, we readily acknowledge that the looseness in the definition of our operator means that all of our so-called results are highly speculative. Plans for future work with the new operator are discussed in the last section.

An important reason for the tremendous interest in metaphor over the past 20 years stems from cognitive linguistic research. Cognitive linguists embrace the idea that metaphor is not merely a part of language, but reflects a fundamental part of the way people think, reason, and imagine. A large number of empirical studies in cognitive linguistics have, in different ways, supported this claim. My aim in this paper is to describe the empirical foundations for cognitive linguistic work on metaphor, acknowledge various skeptical reactions to this work, and respond to some of these questions/criticisms. I also outline several challenges that cognitive linguists should try to address in future work on metaphor in language, thought, and culture.
